I Miss a rule like
ACCEPT udp -- anywhere anywhere udp dpt:dhcp
in your setup
dhcp-requests uses the udp-protokol and the port 67
See the following output on my fli4l-router-machine (dnsmasq is
configured as dns and dhcp-server)
netstat -nap | grep dnsmasq
tcp 0 0 0.0.0.0:53 0.0.0.0:*
LISTEN 3510/dnsmasq
udp 0 0 0.0.0.0:53 0.0.0.0:*
3510/dnsmasq
udp 0 0 0.0.0.0:67 0.0.0.0:*
3510/dnsmasq
Cheers,
Peter
